[bug] q.a = class {} resolves to undefined

[SeregPie]

Here is an example.

---

input

const q = {};

q.a = class {
  c () {}
}

output

var q = {};

q.a = (function () {
  function undefined () {}

  undefined.prototype.c = function c () {};

  return undefined;
}())

---

This way it is working fine.

const q = {};

Object.assign(q, {a: class {
	c () {}
}})
